Document Type and Number:
WIPO Patent Application WO/2011/021288
Kind Code:
A1
Abstract:
A vibration damping device for suppressing lateral vibration generated in an ascending/descending body of an elevator, wherein a coil (15) provided on the movable element side of an actuator is made to be firmly held relative to a bobbin (14) to prevent the coil (15) from sliding slightly. To achieve this, the bobbin (14) of the movable element has formed therein a groove (19) extending in the direction of winding of a winding wire of the coil (15) on a bobbin (14). The winding wire (18) is wound in the groove (19) to form the coil (15), the entire coil (15) is united, and each of adjacent portion of the winding wire (18) forming the innermost layer of the coil (15) is made to be in contact with each other and is, in a lateral cross section, made to be in contact with a portion of the groove (19).
